    Assessment of objective functions under mobility in RPL
    (Springer Verlag, 2018) Sanshi, S.; Jaidhar, J.
    Due to the technological advancement in Low-power and Lossy Network (LLN), the sensor node mobility has become a basic requirement. Routing protocol designed for LLN must ensure certain requirements in a mobile environment such as reliability, flexibility, scalability to name a few. To meet the needs of LLN, Internet Engineering Task Force (IETF) released the standard IPv6 Routing Protocol for LLNs (RPL). RPL depends on Objective Function (OF) to select optimized routes from source to destination. However, the standard did not specify which OF to use. In this study, performance analysis of different OFs such as Objective Function zero (OF0), Energy-based Objective Function (OFE), Delay-Efficient Objective Function (OFDE), and Minimum Rank with Hysteresis Objective Function (MRHOF) is carried out under different mobility models, which makes this study unique. The metrics used to measure the performance are latency, packet delivery ratio (PDR), and power consumption. Simulation results demonstrate that under different mobility models, MRHOF achieved better results in terms of PDR and power consumption, while OFDE shows better results in terms of latency compared to other OFs. © Springer Nature Singapore Pte Ltd. 2018.

    An energy-efficient static multi-hop (ESM) routing protocol for wireless sensor network in agriculture
    (Institute of Electrical and Electronics Engineers Inc., 2018) Dubey, A.K.; Upadhyay, D.; Santhi Thilagam, P.S.
    Energy efficient routing is a crucial area of research for wireless sensor network(WSN). The communication between the wireless sensor nodes is handled by the routing protocols. The nature of the link, low power and limited recourse makes it a difficult task to design an energy and performance efficient routing protocol for WSN. This paper proposes an energy-efficient route selection protocol for a multi-hop network with a static link for deployment in the field of agriculture. An energy model is also given in this paper to evaluate the energy consumption of the network. The proposed energy-efficient static multi-hop(ESM) routing protocol is evaluated based on the performance parameters for energy efficiency, network lifetime and pack loss and compared with an existing scheme. The simulation results represent that the proposed protocol increases the network throughput and the lifetime. © 2018 IEEE.

    Routing Criteria for Low Power and Lossy Networks
    (Institute of Electrical and Electronics Engineers Inc., 2021) Kamble, S.; Chandavarkar, B.R.
    The network types are getting updated from wired to wireless and wireless to Low Power and Lossy Networks (LLNs) based on the applications. Hence there is a need for a routing protocol that supports the latest properties of the network. The paper reviews the criteria defined by ROLL for LLNs. The paper also provides a discussion on how some of the protocols behave in context to these criteria. The paper also mentions the requirement of various categories of loT applications. A protocol that satisfies the criteria is considered to be suitable for LLNs with some necessary features. A protocol should also satisfy the requirements of a wide range of applications so that the protocol designed is reliably used. © 2021 IEEE.
